The attached bell is a huge mistake. Cats have sensitive hearing, and constant ringing with every movement, right under their ears, causes them stress and frustration. If you're buying this collar, I beg you, take some scissors and CUT OFF the bell before putting it on your cat.
Unfortunately, very disappointing. At the spot where you adjust the length, there’s a huge lump because the layers are way too thick. With a small dog, it really stands out and just doesn’t look nice. Such a pity, I have to send it back.
